production of an apparatus which is simple in construction, strong and durable, and

at the same time mexpensive in initial cost and upkeep. Another object of my invention is to provide an apparatus which may .be easily operated by one person, at the same time leaving the operators' hands free forrepair- Another object of my invention is to provlde an apparatus for testing radiators, wherein the radiator is immersed in or raised .from'the tank by means of. foot power. Another objectof my invention is to prov1de an apparatus for testing andrepairing radiators which may be attached to most of the tanks and vats now in use in automobile repair shops. Another object of my invention is to ro- Y vide an apparatus wherein the leaks 1n a radiator may be easily and quickly located without the necessity of handling the radiator. Anot her object of 'my'invention is to provlde an apparatus for testing radiators wherein the supporting frame for the radiator is quickly and zeasilyd'etached Without.v

the use of tools to enable the cleaningof .40 the tank.

The final object of my invention is to provide an ap aratus for'testing and repairing radiators 1n which any part or all of a radiator may be immersed in water for testing, after which the same may be raised free of the water to a position to be repaired,

' without the necessity of the operator using his hands until he is ready to repair any no leaks that may have been found.

upon legs, a frame upon which radiators '0 any shape or size may be placed, and a pecullar arrangement of chains and pullegs for raising or lowering the frame and at t e same time maintaining th'eframein a hori- My invention comprises a tank mountedzontal plane. The power is applied through owermg t e a ,foot lever for raising or radiator supporting frame.

My invention will be more fully understood from the following description, reference bein had to the accompanyin drawmgs whic form a part of this speci cation, in which tion.

Fig. 2 is a front elevation.

Fig. 3 is a plan view.

Fig. 1 is an end elevation of-myv inven- Fig. 4e is a deta1l vlew illustrating the 4 means for supporting the radiator frame. Fig. 5 isa detail view showing the method of securing the chains to the drums Similar characters of reference designate corresponding parts in the several figures f the drawing;

My invention c mprises a tank 1' mounted upon legs 2 in the usual manner. The tank may be filled to\, any desired depth with water or any other li uid that may be used in testing radiators or leaks.

Mounted in such'a manner that it may readily be lowered into or raised out of the tank is a rectangular frame 3, compnsing front and rear bars 4 and 5, respectively,

end bars 6 and 7, and intermediate bars 9, as clearly shown in nections'and joints of this frame are welded Fig. 3. All the contogether and finished smooth on the outside so as not to oil-er any obstruction to e ther the radiator or the hands when repairing leaks. Preferably iron pipe is used in the construction of the frame.

At the corners of the frame are'downwardly-projecting lugs 10, having hooked ends 11 which engage the chains 13, as'clearly shown in Figs. 1 and 4, and it will be readily seen that theohains end links 12 of may be easily disengaged from the hooks 10.

Secured to the legs 2, near the upper ends thereof, are brackets 14, upon which flanged ulleys '15 are mounted to rotate, and simiar pulleys 17 secured to-the legs 2 near the bottom of the tank 1. i

A shaft 18 is hung in brackets 19 .at-

tached to the tank 1, and secured tothe' shafts 18 are flanged 13 are arranged in pairs ad ac ent the ends of the tank, and each chain of a' pair are secured to one. of the drums 20' on the opposite endaof a diametertaken through the 16 have a bearing on brackets drums 20. The chains drum. Cotter pins 21 pass through the ends of the chains 13 and the flanges on the drum 20, a as clearly shown in Fig. 5.

It will be readily seen by inspection of Fig. 1 of the drawin that whenthe drums v20 are rotated by t e shaft 18, the chains 13 willall be wound the same amount upon the drums, and as the. end of each chain is secured to a corner of the radiator frame, .all corners of the frame will be raised to.

- .an equal extent, thereb keeping the frame 1 3 alwa ,s in a horizonta plane regardless of the he1ght of said frame.

- "The shaft 18 is rotated" by a drum 22 similar to the drums 20,and one end of a chain 23 is secured to the drum by a cotter pin, the connection-being the same as that by which the chains 13 are secured to the drums 20. The chain 23 .is fastened at its opposite endyto a foot lever 24 by a in 25, as shown in Fig. 1 ofthedrawing. e

lever 24 is pivoted at 26 to abracket-27 sus ended at the back of the tank 1.

v ecured tothe front of the tank 1, and

to one of the legs- 2, is a bar 28 having -sto s 29 to engage the foot lever 24.

y reference to Figs. 1 and 2 of the drawings, it will be seen that the depth of immersion of .the radiator and the .frame 3, will depend'upon-whichof the stops 29 the lever 24 engages, as it is manipulated b the 0p- ,erators foot. As shown in the rawmgs, the lever 24 is engaged by the lowest stop 29 and the frame 3 and radiator resting thereon is abov'e thetank 1 in a position to be re aired.

il e I have shown my invention rectangular in shape, as seen in plan view, I 0 not limit myself tq any particularform, .as various shapes may su gest themselvesto J those skilled in the mac anical arts without 1 The operation of my invention is as folows:

The frame 3 is raised to the highest position, and the lever 24 held down by the lowest stop 29. The tank 1 is filled to' the desired level with water. A radiator 30 is placed on the bars 9 of the frame 3, and air tubes, not shown," are connected to'said radiator. The operator disengages the foot lever and'lowers' the radiator into the Water from. Havin the desired distance, turns on the air and locates any leaks by bubbles ari there-, located'a leak or le aks, he

' raisesthe radiator by pressing down on the foot lever and engaging the with the lever 24. V I The operator can. now repair the radiator without removing the same from the frame.

W881i S p v After soldering such leaks, the operator can change the position of the radiator on the frame 3 and-repeat. the above 0 ration.- The'soldering can all done wi outtadeparting fromthe spirit of my invenmovin the radiator from'the frame, and all sol er droppings will fall into the tank.

V In the drawings I have shown my invention as a complete unit with tank and supports therefor, but it is to 'be understood that I can and may apply the movable parts of my invention to any make-of tank or vat now 1n use without departing from the spirit of my .invention.

Among the advanggfs of my inventionare the following: us man :can test the largest trucki'adiator without aid or trouble. The radiator is not attached to anything, but lies flat on the frame, and can be moved or set at any an le instantly.

One man can, with the use o this device,

repair a radiatorinsix hours, which would ordinarily take ten hours to accomplish. I

It is'not necessary to touch the radiator with the hands in order to submer e the same.

The device may be used on c eaning vats where the heat or solution is injurious to the hands.

What is claimed is I 1. Inan apparatus of the character de; scribed, a tank, a horizontal frame within said tank, flexible members attached at one endto the frame at separated points for;

suspendin the same, revoluble members over who the flexible members here atthe other end thereof and operable ass, and" means connected to all .of the flexi le'm'emto 1111 each of the flexible members vertisame distance so as to raise the frame, while maintaining its horizontal position.-
